Go for major lash drama.

Sometimes size does matter—when we're talking about lashes, of course. Long mega-thick ones make any woman look instantly sexier, as Miley Cyrus proves. To apply false lashes, don't look straight into the mirror. Put a makeup mirror on a table instead so that you're looking down on it. "You'll be able to see what you're doing, and the strip will land right on the lash line," says celebrity makeup artist Mai Quynh.
